What is the difference between the TC–T and the TC-H?
• The TC-T is a two speed unit (500 and 800 cfm) controlled by a thermostat (included).
• The TC–H is a single speed, 800 cfm unit, provided with a spdt wall switch.

What comes with the TC?
The TCT comes with a wall mount thermostat, The TCH comes with a regular wall switch.

Will I need to purchase anything else?
If you have an insulated roof system you may need a thimble. An interior grille is a popular accessory with the TC-H models.

USE AND CONSTRUCTION
Will the TC work with my pool or spa?
Yes, We strongly recommend the use of a non-chlorine based cleaner.

Are there chemicals that I can use that won’t damage the TC?
Yes, non-chlorine base and the like. Please consult with the pool or spa manufacturer.

Will my TC prevent water from condensing on interior surfaces?
The TC will assist. Most of the causes of water condensation are directly related to temperature differential. Extremely warm, moist air will condense on colder solid surfaces. The closer the two are in temperature the less the condensation will occur.

Can I use the TC to vent heat from my greenhouse?
Yes.

Can I use the TC to exhaust cooking heat and odors?
Yes, but it is not recommended as a substitute for the kitchen range hood.

Will the TC cool my sunroom or living space?

SPECIFICATIONS
What colors are available for the TC models?
Brown or white.

What is the housing size?
Multiple Housing sizes are available, please call us.

What is the rough opening?
The rough opening is 12-3/4" x 27-3/4".

What is the internal thermostat?
The internal thermostat controls the change from low speed to high speed for the TC-T. When the temperature at the TC-T climbs above 90°, the fan will shift from 500 cfm to 800 cfm. When temp at the fan height falls below 90° it will shift back 500 cfm (these temperatures are all approximate).

Do I need a thimble?
If you have an insulated roof system, you may need a thimble. An insulated roof system is made up of a foam panel sandwiched between two sheets of either aluminum or vinyl. The thimble will protect the foam from being sucked into the fans. In most solid roof applications the framing structure acts as the thimble. In some retro-fit applications where the TC will be installed in a previously insulated wall or roof and a complete frame will not be built, the thimble may be necessary. The thimble can be used with either the TC–T or the TC–H.

How do I determine the size thimble I need?
The thimble depth dimension is determined by subtracting 1/2 inch from the overall roof thickness. Overall roof thickness is measured from the outside of the exterior sheathing to the inside face of the interior sheetrock.

What size thimbles are available?
The outside dimensions of the thimble are 27? x 12-1/2?
Available thimble depths are: 2-1/2, 3-1/2, 4-1/2 and 8-1/2. They can be trimmed in the field as needed.

What is the flange?
The flange is an integral part of the housing that is used to mount the TC into the glazing or onto a solid roof or sidewall. The length, width and thickness dimensions of the flange will vary, depending on the glazing system or roofing system in your sunroom or roof.

What determines the flange thickness?
In many applications the TC-T is replacing a glass panel. Individual manufacturers have different glass panel thickness. As an example, a 1" flange is made up of the 1/8" thick upper housing, the 1/8" thick lower housing and a 3/4" thick spacer. The 1/4" flange thickness of the TC–H is the bonding of the upper housing directly to the lower housing.

What is the flange size of the TC-H?
The standard flange size is 36" x 16-5/8" x 1/4". The flange can be altered in the field.

OPTIONS and CONTROLS
Do I need a grille?
No. However, many customers prefer the look of a return air grille in the interior space to the look of the eggcrate grille which is attached to the lower housing.

What size is the grille?
The grille size is 30 x 14 for horizontal installations or 14 x 30 for vertical installations.

What types of controls can be used?
TC’s can be controlled by any SPST wall switch, a line voltage thermostat, electro-mechanical crank pin timer, all types of mechanical closure timers, a line voltage thermostat, standard 2-wire humidity controls or a combination of most any type of line voltage control.

What control is provided with the TC?
The TC–T is supplied with a wall mounted line voltage thermostat.
The TC–H is supplied with a SPST wall switch and cover plate.

What color is the wall mounted thermostat?
White.

What color is the SPST wall switch and cover?
White.

INSTALLATION
Why do I need a 3-wire power supply?
Power to the fan is still necessary, even after you shut the fan off. The damper requires power to close.

Can the TC be mounted on a vertical wall?
Yes. It would be best if the TC were to be located under an overhang or some type of structure that will prevent water from entering the housing when the fan is in opening or closing mode. The TC can be oriented on either a horizontal or vertical plane.

Can the TC be mounted on a flat roof?
Yes. If the roof is “flat” and there is the possibility of standing water or puddles of water a curbing should be built up.

What is a curbing?
Curbing is a build up on a flat roof allowing the TC to sit above potential puddling.

Can I mount the TC on a “standing seam” metal roof?
The customer should contact the roofing manufacturer for instructions.

What if I have an insulated roof system?
If you have an insulated roof system, you may need a thimble. Please see Specifications.
